A machine (1) for extracorporeal blood treatment comprises a device (2) for ultrafiltration of a liquid through a semi-permeable membrane (3) of a blood treatment device (4), a first sensor (11) for ultrafiltration rate through the membrane, a second group of sensors (13) for measuring a trans-membrane pressure, and a programmed controller (14) for calculating a maximum ultrafiltration rate as a function of the transmembrane pressure. The machine is suitable for kidney failure treatments, such as hemofiltration and hemodiafiltration. In a relatively short time the machine enables a large quantity of corporeal blood to be removed from the patient.
Une machine (1) de traitement extracorporel du sang comprend un dispositif (2) qui effectue l'ultrafiltration d'un liquide à travers une membrane semi-perméable (3) d'un dispositif (4) de traitement du sang, un premier capteur (11) qui détecte la vitesse d'ultrafiltration à travers la membrane, un deuxième groupe de capteurs (13) prévus pour mesurer la pression transmembranaire et un dispositif de commande programmé (14) qui calcule une vitesse d'ultrafiltration maximale en fonction de la pression transmembranaire. Cette machine est appropriée pour effectuer les traitements d'insuffisance rénale, tels que l'hémofiltration et l'hémodiafiltration. En un temps relativement court, cette machine permet d'extraire une grande quantité de sang corporel du patient traité.
